FIREARM.

To all whom it may concern:

' Be it known that I, TIMOTHY F. HORAN, of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Firearms; and I do hereby declare that the followin is a full, clear, and exact descri tion thereo which will enable others skille in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the reference numerals marked thereon, which form part of this specification.

My present invention relates -to an improved'fire-arm or a rifle having a pumpaction, by the operation of which the loading and firing mechanisms are operated and the empty shells extracted.

My invention is illustrated as applied to a high power rifle having a rotary magazine and a breech block sliding to and fro by mechanism which operates at the same time to place the cartridge and to cook the rifle ready for firing.

The object of my invention is to provide a fire-arm of the class described which is of improved and simple construction and is durable, eflicient and safe in operation.

A further purpose of my invention is to provide a fire-arm having improved means for locking the breech block in closed position and rendering the fire-arm safe when it is loaded and cooked.

A further purpose is to provide a fire-arm wherein the operatin block forms a means 1for locking the breeci block in closed posiion.

A further urpose is to provide in the fire-arm already described improved means for releasing the locking device without pulleing the trigger.

A still further object of my invention is to provide improved and elficient means for preventing the pulling of the trigger and the dischargin of the gun until the breech block has been rought to closed and'locked position and also to provide improvedmeans for allowing the breech block-to'be to closed osition but not locked.

A still urther intention of my invention is to provide improved means for ractically cocking the fire-arm as the breec block is being moved back to open position;

Another object of my invention is to' provide an improved construction of fore-end brought Specification 01' Letters Patent.

take-down, by which is meant the feature. of having the barrel and fore-stock and the sliding member on the fore-stock readily detachable from the receiver and its attached mechanism and the rear part of the operating rod, in order to reduce the length of the fire-arm and place it in more compact form as for carrying, transportation or storage or for cleaning the fire-arm.

A further pur ose is to provide a pum action fire-arm 0 such construction that t e operating rod is entirely housed.

Further purposes and advantages of my invention will appear from the specification and claims herein.

Figure I is a side view on a reduced scale of a fire-arm embodyin my invention.

Fig. 2 is a central on 'tudinal. section about actual size through t e fire-arm, with the rear part of the butt stock and the forward part of the barrel and the forward part of the fore-stock removed, the parts bemg in the position'they occupy when the fire-arm is cooked.

Fig. 3 is ,a view, drawn to the same scale,

partly in side elevation and partly in secof the breeclij block, operating block, ad] nt part of theoperating rod and connected locking device, with parts of the receiver in section, showing the operating block locking the breech block in closed osition and the other locliing device holding the operating block In forward position.

Fig. 6 is a side view of the operating block, showing the side opposite to that seen in Fig. 5.

Fig. 7 is a top view of the operating block and means for looking it in forwar pos tion.

Fig. 8 is a longitudinal section similar to Fig. 2, but with thearts in the position they occupy when the reach block is in retracted position. Y

Fig. 9 is a cross section on line 9--9 of are top and side views respectively of the forward half of the operatin rod. Fig. 15 is a view from below of the orward end of the rear half of the operating rod.

Referring to the drawings in a more particular description, there will be seen the metal receiver 20, to the rearward part of which is secured the usual wooden butt stock 21, While to the forward upper end of the receiver is detachably secured as by partial screw threads 22 the rear end of the barrel 23. The breech block 24 is slidingly mounted in the receiver so as to be moved forward and upward to closed osition and to be moved down and rearward y to retracted position.

In the breech block there is slidingly mounted the hammer 25, to the forward end of which is secured the usual firing pin 26, while the main spring 27 surrounds the hammer and is so connected to the hammer and so placed in the breech block as to force the hammer and firing pin forward when the hammer is released. Depending from the rear end of the hammer 25 is a projection or dog 28, whereby the hammer is placed under tension preparatory to firing and so held under tension by the sear 29 until the tugger is pulled.

Integral with or firmly secured to the breech block 24 toward its rear end is a side plate 30, which extends rearwardly of the reach block and for some distance below the breech block, said side plate being upon the farther side 'of the breech block as the parts are seen in Figs. 2, 4 and 5. In the surface of said side plate toward the center of the breech block is a groove 31 slanting downwardly and forwardly and having its lower end open as plainly seen in Fig. 4-. On the near side of the rearward portion of the breech block there 'is rovided a downwardly extending smaller p ate or ear 32, clearly shown in Fig. 5.v Between the side-plate 30.

and the ear 32 there is a longitudinal openlng adapted to reeeivethe operating rod 33 w en thdbreech block operating rod 33 and operating block 34 are moved to rearward position. y a

In the forward lower part of the receiver 20 islocated a circular m ine carrier 35 rotatably mounted u on a ollow shaft 36, in which -hollow sha is slidingly mounted the operating rod. 33. As 'shewnin Fig. 8

the hollow shaft inay be omitted and the darrier mounted directly-upon this operating rod 33 Upon the rear endof the operating rod--33 is rigidly fastened the operating block 34. y A 7 Onthe farther side of the operating block asathe parts are viewed in Figs. 2 a-and 5 or upon the near side as the operating block is in Fig.3 and at the forward and u pereomer of the operating block is pror wand a outwardly projecting pin, 37 extending transversely of the receiver. I prefer to mount upon this pin an anti-friction roller 37 in order to make the coiiperating parts move more readily, but it will be obvious that a pin without such an anti-friction roller will perform the necessary functions and for the purpose of clearness in the de seription hereafter I will speak of said pin as engaging given parts, whether the said in is supposed to be provided with the antiriction roller or not.

The main part of said operating block is located on the near side of the side plate 30 and the pin 37 takes into the groove 31. With the parts in the position shown in Figs. 2 and 5 the said pin 37 rests in the open forward end of the slot 31. Rearward motion of the operating block 34 communicated through 0 rating rod 33 from the handle 38 hereinaiiir described will cause the pin 37 to bear with a summing action against the slanting rearward side of groove 31 in side plate 30. By reason of the fact that the operating rod 33 is held to motion in a straight line by means of its long sliding bearing in the hollow shaft 36, it will be seen that the operating block 34 is. held to motion in a similar direction and cannot move upward. Rearward motion therefore of operating block 34 will cause the pin 37 as it engages the said slanting rear side of groove 31 to force the rear end of the breech block 24 downwardly until the shoulder 39. of said breech block is free of the forwardly facing shoulder 40 0f the receiver 20. Then the top of the breech block 24 is free to slide rearward along the downward facing surface 41 of the receiver 20 and does so slide, through the fact that the pin 37 'has reached the rear and substantially upright portion of the groove 31, so that rearward motion of the operating'block 34 produces a similar rearward motion in the side late 30 and the breech block 24 connected t ereto.

As the breechblock' has thus. moved to retracted position, clearly shown in Fig. 8, the cartridge held by the breech block has been withdrawn from the barrel; released from the breech block and thrown. out of the receiver and a new cartridge hasbeen moved upfrom' the magazine into osition where it is grasped by the forwa end of the breech block, all by means common to this class of magazine fire-arms and therefore not necessary to be described here in detail. V

Upon the rear upper and" near corner of the operating block 84 there is an upwardly extending projection 42. which when the parts are in cocked position as shown in igs. 2 and, 5' is to the rear of the small plate 32 and in front of. but'in line with, the hammer, dog 28 even after the fire-arm has been fired. Soon after the rearward motion of the'operating block 34 begins, as heretofore described, the upwardly extending projection 42 on the said operating. blockcomes into engagement with the forward side of the hammer dog 28 and begins to force the hammer rearwardly relative to the breech .block,-fo rthe reason that the direct rearward motion of the breech block has not yet be and o the roove 31 and direct rearward motion of t e breech block 24 begins the breech block, 0 crating block and hammer move rearwar y together and without further longitudinal movement relative to eachother, and with the hammer retracted to almost its rearward position relative to the arts come to rearposition as shown To the rear and at the bottom of the operating block 34 said block extends toward the farther side of the receiver to a point about even with the farther side of "side plate and is there provided with a forwardly and upwardly extending11 finger 43, ..e.ngagin the farther side of t e side plate 30 an operatingi block and operating 1) ock in proper relation in certain positions of said parts.

@ rounded at some distance by the usual trig- 'Uioii the sear screw 44, suitably secured m .t e receiver 20 and extending transversely thereof, is pivotally mounted the forward end of the sear 29, which extends rearward and has its rear endloosely connected to the forwardly extending end of the trigger as by means of the forward end of said trigger having its end placed in a recess 46. in the rearof the sear 29 as plainly indicated in Fig. 2. The trigger '45 is pivotally mounted upon a pin 47 provided in the receiver, while the finger-engaging portion 48 of the trigger extends ownwardly through the receiver and 1s surgcr uard 49. A trigger spring 50 mounted in te receiver yieldingly holds the trigger in normal position, that is, with its forwardly extending arm upward and its finger portion 48 forward. As the trigger is thus held in normal position the sear will be heid in corresponding upward position, While pull ing upon the trigger will depress the sear.

As the parts move to the fully retracted position shown in Fig. 8 the operating block 34 moves rearwardly in a straight line, dueto the long bearing of the operatingrod 33 and also due to the fact thatthe bottom of the block is resting directly upon the straight surface 51 in the lower .part. of the cavity of the receiver 20. As the breech block 24 travels back, its rearend is first depressed as already described and then its upper surface travels back, sliding upon the surface 41: of the receiver until the parts come to fully retracted position as shown in Fig. 8. As the breech block thus travels As the pin 37 comes to the rear to keep the breech back and downward, the bottom of the side plate 30 travels along the bottom-line of a groove 52 in the lower part of the receiver, whichslants downward relative to the slide: way 51 as the rear of the receiver is ap- :proached, as plainly indicated in Figs. 2

and 8.

It will thus be seen that as the breech block 24 and operating block 34 and their attached parts move rearward, the breech block and operating block are brought closer together and the forward surface of the hammer 'dog 28 has moved down relative said parts during such motions I prefer to provide a. small roller 54 on pin 55 close to the lower end of the hammer dog 28 and with the forward part of the roller projecting slightly forward of the forward surface of the hammer dog so that the rear edge 53 of the operating block 34 bears upon said rollers 54, while the operating block and hammer dog are sliding toward and away from each other. As the operating parts move rcarwardiy toward the retracted position shown in Fig. 8, the rearward portion of o crating rod 33 moves into the recess provided between the breech block side plate 30 and the smaller and nearer plate 32, while the upwardiy extending point 42 on the rear upper side of the operating block 34 passes up partly by the extreme rear end of the operating rod 33 and on the near side thereof.

Forward movement of the operating handle 38 communicated to operating rod 33 draws the operatin block 34 forward in a straight line. As t e operating block 34 so moves forward, itspin 37 is engaging the upper or vertical portion of groove 31 in the side piate 30 and so giving a corresponding forward motion to the breech block 24, which block is-about to take place. At this time the hammer dog 28 and particularly its roller 54 has just come into contact with the rearward edge of the sear-29. Further forward motion of the operating block moves the breech block forward to closed position 7 and sharpiy raises the rear end of the breech block, due to the fact that the pin 37 on the farther side of the operating block new engages and slides through the downwardly and forwardly inclined portion of the groove 31 in the breech block side late 30 with a camming action, which is assisted by the forward upper corner of the operatin block having a similar cammin action with the downwardly and forwar ly slanting edge 32 of the small side plate 32 upon the near side of the breech block so that an upward fully closed and forward motion is imparted to both edges of the breech block until it has come to final forward and upward position, as clearly shown in Fig. 2, with the rearward] facing shoulder 39 of the breech bloch closely engaging the forwardly faci shoulder 40 of the receiver and the upwar y facing shoulder 56 upon the rear portion of the breech block engagin the forward portion of the downwardly acing guideway 41 of the receiver, which last e ement prevents the rear end of the breech block being forced. too high.

It will now beobvious that as long as the rear end of the breech block is held in this upward sition, it cannot move backward and so t e breech block will be locked in osition. The locking of the breech block 111 this fully closed position is positivel efl'ected through the fact that as clearly s own in Figs. 2 and 5-the operating block 34 has moved directly beneath the rear end of the breech block, with the upper sur face of the operating block resting squarely and flatly beneath the lower edge of the near small side plate 32 and with the transversely extending or broadened lower part 34 of the operating block, closely engaging the lower edge of the large side plate 30, as particularly shown in the sectional view, Fi 9,

while the bottom of the operating bloc 34 rests for most of its length and for all of its width squarely upon the face 51 of'the receiver. It will be understood in fact that in all of its positions the bottom of the operating block 34 is upon this surface 51 of the receiver, thus materially assistin to hold the operating block in proper position and particularly relieving t e operating rod 33 from any twisting strain while the operating 'block is being moved forward and is exerting its camming efiiect in raising the rear end of the breech block;

' During the short final forward movement of the breech block of about an ei hth of an inch in extent while the breech -b ock is be.- ing moved upward to closed position the hammer dog 28 or its anti-friction roller 54 has been engaged, by the rear H of the sear 29 and so the hammer has n held longitudinally stationary while the breech 1 block has been moved forward for said eighth of an inch or so and the cockmg operation has been completed'by thehammer being drawn rearward relative to thebreech block. While' the rearward end of the -tive to the sear and the relative slidin breech block has been thus moved upward,

the dog 28 has of coursemoved upward rela- I motion between the forward edge of the ammer dog and the rear edge of the sear has been substantially relieved of friction through the presence of the roller 54. In

order to prevent any accidental discharge of therifle, due to too free a slidin movement of the sear 29 upon the roller 54, t ore is provided a very slight rearward projection 57 upon the upper part of the rear edge of the sear, which obviously will prevent the sear swinging downward throu any shock the fire-arm may receive and yet permit the usual pulling of the trigger 45 to depress the sear and so disen ge the sear fromthe hammer dog 28 and low the hammer 25 to jump forward and fire the rifle in the usual way.

To prevent rearward movement of the opcrating block 34 after the breech block has come to fully closed locked into that position by said operating sition and has been block as heretofore described, there is provided an action lock, which holds the said parts in closed osition and locked position until the said action lock is urposely released. Phis action lock consists of a trigger-like bell crank 58 loosely pivoted upon .a

in 59 in the lower part of the receiver 20 in such manner that the forward end of the forwardly projecting armof the bell crank 58 takes into a recess 60 provided in the bottom of the operatin block immediately adjacent to the near si e of said block when the operating block is in full forward position, as lainlv indicated in Figs. 2 andu5.

he bell crank 58 of this action lock is pivoted on the pin 59 loosely enough to allow the forward end of the forwardly extending arm to swing sidewise an appreciable distance. A small spring 61 is interposed between the forwardly. extendin arm of the action lock 58'and a portiono the receiver immediately therebelowso as to yieldlngl hold the forward 'end of the action above the surface 51 .u n which the operating block 34 slides. diagonally mounted transversely of the receiver, with the upperend of the spring farther over in the receiver than in its ower h 61 is also e spring 1 end as the parts are viewed 'in Fi 2, 5 g

and 8, resulting in the forward on of, the said. bell crank 58 being. yieldingly pressed toward the farther side of the receiver; As the operating block is being moved forward to forward sition the forward end of the hell crank 5 is engaged by an inclined surface 34* on the orward lower corner of the near side of the operating-block 34 and moved out even with the near side of the said block until the blgck has come to full forward position, when the forward end of the action lock bell crank under the'diagonal tension of spring 61 moves sidewise or 29 incident to the firing operation causes the lower edge of the sear, which is on the near side of the operating block 34, to bear down upon the upper side of the forwardiy extending arm of the bell crank 58, which is of such width and so placed as to have part of its width beneath the sear. This temporary downward depression of the action lock causes its forward end to be disengaged from the recess 60, whereupon the diagonal arrangement of the spring 61 at once swings the forward end of the bell crank farther over in the receiver to a point where it is free of the recess 60 and engages the plain bottom surface of the operating block. It

will thus be seen that pulling the trigger automatically releases the, action lock so that as soon as the firin o eration has taken may be moved rearwardly and the breech block likewise moved from closed and locked position. When it is desired to purposely release the action lock without performing the firing operation, this may be done by the operator pressing backward upon the downwardly extending arm of the action lock 58, which,

as plainly shown in the drawings, extends down through an openin in the receiver at the forward end of the trigger guard. Such manipulation of the action lock disengages its forward end from the recess and allows the diagonally arranged spring to move the forward end over clear ofthe locking recess 60 in the same way and with the same result as above mentionedwhen performed by the firing operation.

As a guard against the fire-arm bein fired until the breech block has come to fill forward position and has been positively locked in such position there are provided the following means. Upon the near side of the operating block 34 there is provided, as plainly shown in Fig. 5, a small pin 62 ex- .tendingoutwardly and adapted as the operating block comes forward to slide into either slot 63 or 64 provided upon the farther side of the sear 29 according to the position of the sear at that time. The form and location of these siots 63 and 64 are plainly shown in dotted lines in the side-view of the sear shown in Fig..10 and in full lines in Fig. 11. The slot 63 has its rearward end atthe rear edge of the scar and extends forwardly to the forward position of pin 62 or to the position occupied by the in 62 when the operating block 34 is in ull forward position. From there the said slot 63 extends upwardly nearly to the to of the sear.

The slot 63 is so located upon e sear as to be in line with the pin 62 on the operating block when the operating block comes forward and the sear is in normal raised position.

It will therefore be seen that with the sear in normal raised position the said pin will come into said slot and follow the same to its forward end without moving the sear as the operating block ismoved to forward position and will allow the sear to be depressed and the firing operation to take place when the operating block is in full orward position, by reason of the fact that with the parts in that position the sear can be moved downward, because the upwardly extending part of the groove 63 is opbposite the pin 62 and allows the sear to e depressed as required in firing. The scar, however, cannot be depressed pntil the operating block has come to extreme forward position, because until that .time the pin 62 is in the horizontal part of the slot 63. As the operating block cannot come to extreme forward position until the breech block has been moved to full forward position and positively locked by the operating block coming to extreme forward position thereunder as heretofore described, it will be seen that the means h'ere provided prevent premature firing operations from taking place. a

When as in certain conditions it is desired to move the breech block to closed position and release the hammer, but still prevent the firing pin from coming into contact with the primer, this may be done through the trigger being depressed as the breech block is going forward. Under such circumstances the pin 62 upon the operating block will enter he slot 64 which is provided upon the farther side of the sear 29 above the horizontal part of slot 63 and extends forward nearly to the pointoccupied by the pin 62 at the extreme forward position of operating block 34.

The operating block 34 has its backward and forward motion imparted thereto through the operating rod 33, which extends forward through the central opening in the circular cartridge carrier 35 and may be slidingly mounted directly next to said ourtridge carrier 35 as shown in Fig. 8 oroma be in sliding contact with the hollow sha 36'provided Within the circuiar opening of said carrier as shown in Fig. 2. Beyond said' magazine carrier the operating rod extends and extending for some distance thereheyond, is connected to the operating handie 38-.

The forestock 66 is shown in side elevation in Fig. 12 and in longitudinal central section in Fig. 3, and in top or plan view in Fig. 13, At the extreme rear end of the forestock 66 is an annular portion 67 adapted to fit into the forward end of the receiver 20 below the barrel 23. Immediately forward of this part isa portion 68 which is forward of the receiver and has upwardly extending ears 69 on each side adapted to bear against the outer portion of the barrel-receiving part of the receiver and so assist in preventing improper rotation of theforestock when it is in place upon the fire-arm. From thislarge part68 of the forestock there also extends upward,-

preferably on the center line of the barrel and forestock 2. lug 70, which takes into a slot 71 provided in the lower rearward part of the barrel 23 and also into a registering slot in the lower part of the receiver, wherea slides through the lower part of the large tubular portion 72, with the rear half 33 of the operatin rod extending through the opening in t e rear part of said tubular portion 72, while the forward half 33 of the operating rod extends through the front openmg. of said large tubular part 72 and extends forwardly immediately below the smaller tubular portion 73 and preferably havin its upper surface fit the curve thereof. T e from; half 33 of the operatin rod has its forward end formed into a tu ular sleeve 74 slidingly fitting upon the smaller tubular portion 73 of the forestock and thereby holding the forward half 33 of the operating rod slidingly in place upon the forestock. A rearwardly (gpening slot 75 is provided in the upper sur rise of the sleeve 4 to prevent the cove rtion from striking the hooked lug 76 as t e operatin rod is moved rearwardly. The hooked lu 6 is socurely fastened to the lower si e of the barrel 23 and when the parts of the fires-arm are assembled projects down through an opening 77 provided in the upper side of the a smaller tubular portion 73 of the forestock and into a slot 99 in the latch piece 81' and the forward .lower portion "(8 of said lug engages the interior lower surfaw of theforestoclgrwhile the rearwardly facing hook 79 efthe lug engages the lower side of the forwardly extending lip 80 of, latch 81 mounted within the small tubular part 73 of the forestock. The latch 81 is in the form of a circular pistonslidingly fitting that part of the forestock and yieldingly held in orward positionas by a coiled spring "82 mounted in a rearwardly opening pocket 83 in said latch iece,

which spring bear resplectively upon the forward end of said poc et and upon a pin 84 secured in the walls of and extending transversely of the part 73 of the forestock and through op 'osltely located slots 85 in the rear part 0 the latch piece 81. The length of the slots 85 limits the rearward movement of the latch piece in the forestock.

The upper face of the lip 80 and the portion of the lug 76 below the hook 79 are m camming relation to each other so that as the parts are bein assembled the pressing together of the arrel with its downwardly extending lug 76 and the forestock with its slidingly mounted latch will cause the latch to temporarily yield rearwardly and allow the book of the lug to ass the lip of the latch, when the latch Wlll again slide forward and en age the lug and so hold the forestock and arrel together. Near the forward end of the latch 81 is provided a forwardly facing shoulder 86, which may be reached by the finger or thumb through a proper opening 87 in the lower side of the containing part 73 of the forestock, whereby the latch may be temporarily moved rearwardly by the operator and so allow the forestock to be moved away from the barrel and'then taken from'the fire-arm.

For the convenient manual operation of the operating rod 33 and 33 with the proper pumping action of the hand there is provlded a hollow handle '38, the forward end of which closely fits the sleeve Hand is secured thereto as by screws 88 extending thro h the handle into 0 enings 89 in said s eeve 74:. To the rear Q said sleeve the handle 38 is bored to a larger opening to slidingly fit the exterior surface of the larger tubular part 7 2 of the forestock. In the u per part of the handle 38 is a longitudina y the opposite ends of The lower edge of the lowerand forward endflfi of the lug 76 is purposely allowed to engfigethe forestock at a oi as far forward o'fthe lip 80 of the possible, In order tovgivea slight u ,w d tension to the rear end of the forestocE' a, so hold the parts more firmly together a" "revent an poss ble motion or rattling feparts 23' when the forested: and barr ol a being carmed together but separated vfrom the reeel-vet.

As a further means of reventin longitudinal disengagement of t e joint w en once connected, there are provided upon said tongue outwardly extending cars 96, the rearward faces of which engage the forwardly facing hooks 97 upon both sides of the split rear end of the operating rod 33 or to either side of the recess 92 I It will now be obvious that the joint may have its lparts connected bytpassing the.

slot 92 over is e tongue 91, with e forward half of the operating rod 33 slanting downward relative to the rear half 33 of the operating rod so that the knob 93 is over the recess 94 and the hooks 97 are over and to the rear of the cars 96. Then by raising the forward art of the front half of the operating rod the parts of said joint are locked together and will stay locked as long as the two halves of the operating rod are in line a with each other. a a y The forestock is readily detached from the barrel and receiver of the fire-arm by moving the operating rod and operating handle 38 to rearward postion, thus uncovering the opening 87 on the forcstock and allowing the operator to slide the latch 81 back so that its lip 80 is disengaged from lug 76. Then swinging the forward end of the front half of the operating rod with its attached handle downwardly will reverse the locking movement of joint 65 and so allow the front half 33 of the o eratin rod to be detached from if 33.0 the operating rod. The barrel 23 may then be readily detached from the receiver 20, If necessary, the hooked log 76 upon the barrel may be usedto obtain the necessary twisting hold upon the barrel. An opening 98 in the upper part of the large tubular portion 72 of the forestock is provided to receive said lug 76, whereby the forestock'may be used as a handle to rotate thebarrel from the receiver. To re-assemble the parts of the fire-arm thebarrel is first placed in position upon the receiver. Then the annular portion 67 of the forestockis placed in the receiver, with the forward part of the forestock away from the barrel and with the lug of the forestock enga 'ng the" the barrel willlock the two parts of the operating rod at the joint 65 and final movement of the forestock against the barrel will cause the hooked lug 76 .to force the latch 81 temporarily to the rear and then the latch will enga the hook of the In as already described in detail and thus hoqd'the parts of the fire-arm securely to ether.

What I- claim as new an desire to secure by Letters Patent is:

1.
